The video provide a method to enhance reliability of Cisco ASA CX Passive Authentication by integrating Cisco ISE with CDA. You will see how the caveats inherent to CDA can be solved by using realtime user and IP information provided by 802.1x identity-based authentication network. We will analyze RADIUS packets being communicated between Cisco ISE and CDA to try to understand the underlying mechanism. Testing will be performed on both domain and non-domain devices, that have been onboarded through ISE, and this includes both wired and wireless.

The video shows you the second method of obtaining user identity on Cisco ASA CX using Passive Authentication. We will leverage the User-to-IP mapping information provided by CDA by configuring CX device as a consumer. Once the mapping information is available to CX, minor modification will be performed on the Identity Policy and you will see how users are saved from having to enter their credentials as we saw in the Active Authentication. We will also discuss and demonstrate some caveats to this method towards the end of the lab.

The video walks you through an installation of Cisco Context Directory Agent (CDA) server. We will start by prepping a non-domain admin service account for CDA to use to contact Windows Active Directory. We will then step through a virtual machine creation, software installation and patching. We will also spend some time on the CDA web interface. By the end of the lab, we will be able to have CDA monitor user AD login activities and create user-to-IP mapping information that we will leverage in the future videos. 

The video shows you the first method of obtaining user identity on Cisco ASA CX using Active Authentication. We will integrate CX with Windows Active Directory to perform user authentication as well as user group query. We will redo our access policies from the previous lab and replace the source IP subnet with AD user group. This would be our first step towards identity-based access policies and free ourselves from the use of just IP addresses.
